It cost $6 per hour to water the grass. how much will it cost to water the grass for 7/3 hours

Answer 1

start by writing a relation

`\begin{gathered} 1hour\longrightarrow\text{ \$6} \\ (7)/(3)hour\longrightarrow x \end{gathered}`

find x using the relationship

`x=((7)/(3)\text{hour)}\cdot\frac{\text{ \$6}}{1\text{hour}}`
`x=\text{ \$14}`
